FEATuRES BENEFITS ❚ Premium, heat-treated, micron-graded aluminum oxide ❚ Consistent finish and superior cut rate

❚ Patented, high-performance, durable, reinforced resin bond system

❚ Higher MRR with better surface finish

❚ Improved reinforcement and retention of grain for improved cut performance

❚ Compliant layers improve surface finish

❚ Improved interfacial adhesion between film backing and make coat layer contributes to scratch-free, uniform finishes (as no loose grain to cause random scratches or rolling-indentation defects)

❚ Uniform 5 mil polyester film backing with a new non-abrasive, slip-resistant back-coat layer

❚ Extremely durable and tear resistant

❚ Slip-resistance results in consistent wear and part finish

❚ Non-abrasive formula reduces tool wear in powertrain applications

❚ R backing (Rough) for optimal friction; S backing (Smooth) for higher concern with wear

❚ Extensive grit range: 80-9 micron ❚ Comprehensive grit offering for key target microfinishing film applications

❚ Color coded by grit size ❚ Eases identification; minimizes application errors

❚ Available in straight- and scalloped-edge rolls ❚ Scalloped-edge rolls are custom designed to be the perfect fit for finishing diesel crankshafts, fillets, radii, and curved parts – generating superior part tolerances

❚ High-precision edge cutting: +/- 0.002” (+/- 0.05 mm)

❚ More suitable for softer shoes (such as polyurethane), where higher friction and gripping are required

❚ Front and backing are color coded by grit

❚ More suitable (creates less wear) on harder shoes (diamond), where less friction and gripping are required

❚ Excellent choice for roll finishing

❚ Front: color coded by grit
